A Grunka Lunka is a type of Alien race. They are small orange men with green hair. In an attempt to cover up the true nature of Slurm, the Slurm Worms pay the Grunka Lunkas to work at the fake Slurm Factory whenever tourists visit. They try to sing and dance but are stopped by either Bender Bending Rodríguez or Glurmo. They finally sing a whole song but are then denied their bathroom break.
